-// are always internally monitored; but users will only be
-// notified of these events they are interested in. So we
-// no longer have to change the event mask with SetNotify()
-// in internal functions like DeferRead, DeferWrite, and
-// the like. This solves a lot of problems.
-
-// GRG: I added m_error handling to IO operations. Now,
-// wxSocketBase::Error() correctly indicates if the last
-// operation from {Read, Write, ReadMsg, WriteMsg, Peek,
-// Unread, Discard} failed. Note that now, every function
-// that updates m_lcount, also updates m_error. While I
-// was at it, also fixed an UGLY bug in ReadMsg.
